GridView query issues

The datasourceid is implemented with the data source control, and the datasource is the dataset used. Remove = sqa; Plus = ds; Besides, I don't have you = sqa; usage, the following value should be the id of the data source control

How did you comment the data source?。。。 Dizzy!

With the DataGridView control, you can display data and data from many different types of data sources.

Binding data to the DataGridView control is simple and intuitive, and in most cases, you only need to set the DataSource property. When binding to a data source that contains multiple lists or tables, simply set the datamember property to specify the string of the list or table to bind.

The DataGridView control supports the standard Windows Forms data-binding model, so the control binds to an instance of the class described in the following table

Any class that implements the ilist interface, including one-dimensional arrays. Any class that implements the ilistsource interface, such as the DataTable and Dataset classes. Any class that implements the ibindinglist interface, such as the bindinglist(of t) class.

Any class that implements the iBindingListView interface, such as the BindingSource class. The DataGridView control supports data binding for the common properties of the objects returned by these interfaces, and if you implement the iCustomTypeDescriptor interface on the returned objects, it also supports data binding for the collection of properties returned by the interface.

Typically bind to the BindingSource component and bind the BindingSource component to other data sources or populate the component with a business object. The bindingsource component is the preferred data source because it can bind to a variety of data sources and can automatically solve many data binding problems. For more information, see BindingSource Component.

DataGridView is a form control that has the effect of displaying data in a list in a form. There are many ways to use it... For example, binding a data source...

Actually, this question is complicated by what you think.

The current row is not available after the information is published.

There are two ways to solve it.

Clause. First, the role of your gridview should be to publish messages. Therefore, the published messages can be filtered out, and the unpublished information can be used as the data source of the gridview.

If you want to view published information, you can create a gridview for another instance.

Clause. Second, if you don't distinguish between published and unpublished messages, there are two ways to solve it.

1. When you click Publish, you can use the ID of the Find the Row button to find it;

2. When clicking, judge whether this line of information is published, and if it is published, it will be used;

Get the id of the line and you should be able to add this attribute commandagrument= to your publish, button'<# eval("The name of the field")%

button lb = button)sender;

string name=;

So, you should know how to do it, right? If you really don't know, just say it.
